Patent GB-140518-A (GB)
Title: Improvements in and connected with magneto electric machines
IPC: H02K21/18
Filed: 1918-12-24
Abstract: 140,518. North, R. B., and Allen, A. M. Dec. 24, 1918. Inductor machines. - In magneto-electric machines of the kind wherein a stationary armature h is arranged at one end of the machine and is connected to intermediate poles i to which the magnetic flux is conducted from the main poles by a rotary inductor a, the end plate f that supports the bearing c at the armature end of the inductor spindle k is mutilated so as not to have a continuous metallic path in which eddy currents can circulate. In the arrangement shown, this is effected by forming a gap in the plate through which the intermediate poles i pass and which accommodates a non-conductive disk j adapted to support the bearing c. Alternatively, the plate f may be mutilated by means of diagonal slots.
Patent GB-355466-A (GB)
Title: Improvements in or relating to the treatment of textile materials containing organicderivatives of cellulose
IPC: D06Q1/02
Filed: 1930-07-18
Abstract: Textile yarns or fabrics consisting wholly or partly of organic derivatives of cellulose, such as cellulose acetate or other organic esters of cellulose, or ethyl cellulose or other cellulose ethers, are delustered by applying to them one or more ethanolamines and afterwards subjecting the materials to the action of a hot aqueous medium.  The best results are obtained with triethanolamine, but di- or mono-ethanolamine may also be employed, particularly in admixture with triethanolamine.  The subsequent treatment may comprise treatment with superheated steam at normal or excess pressure.  The ethanolamine may be applied locally in the form of a paste thickened with starch or British gum, to which dyestuffs may be added to obtain coloured delustered patterns on a lustrous ground.  In examples, a fabric consisting wholly of cellulose acetate yarns is (1) padded with a solution of triethanolamine or (2) printed with a paste containing triethanolamine, corn starch thickener, and British gum, with or without glycerine; in each case the fabric is subjected to the action of steam under pressure without intermediate drying.  The process is applicable to mixed materials containing organic derivatives of cellulose in association with other fabrics, e.g. cotton, natural silk, reconstituted cellulose and wool.

Title: Improvements in and relating to a mouthpiece for wind-instruments and reed holder for such a mouthpiece
IPC: G10D7/06
Filed: 1946-07-23
Abstract: 626,478. Wood and like wind instruments; mouthpieces. KJELDSEN, E. July 23, 1946, No. 21931. Convention date, Aug. 28, 1945. [Class 88 (ii)] In a mouthpiece for a wind instrument such as a clarinet or a saxophone comprising a reed for producing acoustic vibrations and two curved surfaces forming the lay along which the contact points of said reed can be displaced under the influence of lip pressure, the reed is clamped resiliently against the mouthpiece so as to be yieldable along the whole of its length when the vibrating part of the reed is pressed on to said lay. In one embodiment, Fig. 4, the reed 1 is held in place by leaf-springs 13 carried by a detachable clamping ring 12, and rests upon the end of a screw 16 and upon the ends 8 of a pair of curved surfaces 7, Fig. 3. Adjustment of the screw 16 rocks the reed on the surfaces 7 to vary the pitch. During playing, lip pressure applied to the reed shortens the vibrating portion and raises the pitch, the yieldable securing means enabling the resulting strains produced to be distributed along the full length of the reed. Pressure of the springs 13 may be adjusted by screws 15. A thin flexible plate 9, Fig. 3, presses against the underside of the-reed to provide air sealing means. In a further embodiment, Fig. 6, not shown, the clamping ring 12 is replaced by a bridge-like structure secured to the mouthpiece and the air sealing means comprises a rubber strip contained in a groove in the mouth-piece. The air seal may be formed by liquid in a trough sealed by the reed.

Patent GB-883177-A (GB)
Title: Improvements in single-sideband speech-transmission systems
IPC: H04B1/68
Filed: 1958-07-09
Abstract: 883,177. Transmission systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 9, 1958 [July 12, 1957], No. 22034/58. Class 40 (4). In a transmission system the speech band is divided in two, the lower band being applied as a modulation to the upper band after this has been modulated on a high frequency and a resulting side band has been frequency divided, reception of this signal requiring detection of the envelope to obtain the lower speech band and a frequency multiplication of the signal followed by a modulation to extract a sideband constituting the upper speech band. The transmitter shown in Fig. 1 takes a speech frequency band from 0.5 to 3.5 kcs. over highpass filter 7, modulates it with 95 kc/s., taking out the upper side-band over filter 10, limits the signal at 11 while at 12, the signal is divided in frequency by 10. The resulting signal covers the band 9.55 to 9.85 kc/s. and is modulated at 13 by the low-frequency speech band from 0.1 to 0.5 kc/s. before transmission to the line over filter 14 which passes the band 9 to 10 kc/s. Detector 30 and the 80-cycle low-pass filter 31 provide a further modulation which indicates the amplitude of the upper band of speech frequency. At the receiver in Fig. 2, a detector 17 provides the speech band from 0.1 to 0.5 kc/s. over band-pass filter 21 and the sub 80-cycle signal over low-pass filter 33 to control the gain of amplifier 34 to reconstruct the original amplitude of the speech frequency band from 0.5 to 3.5 kc/s. The transmitted signal is limited at 18 and its frequencies are multiplied by 10 at 22 to regain the band 95.5 to 98.5 kc/s which at modulator 24 in conjunction with a source of 95 kc/s. reproduces the original upper speech frequency band. In the transmitter a source of 97 kc/s. at 35 holds the frequency dividing arrangement 12 operative at a frequency midway of the range 95.5 to 98.5 so that the arrangement responds with greater speed on average to any particular frequency.

Title: An improved cigarette counting and filling machine
IPC: B65B19/10
Filed: 1927-08-24
Abstract: 290,480. Lerner, F. Aug. 24, 1927. Packeting cigarettes in receptacles.-In a cigarette counting and filling machine, the cigarettes arranged in filling hopper and counted are ejected on two sides thereof alternately. Cigarettes are placed in a hopper 1, Fig. 2<a>, having fixed sides 20, 21 converging to a mouth of smaller size than the area of the counting spaces 2 beneath it, the cigarettes falling into the space beneath the mouth and being there shaken up by springy or pivoted members 22, 23 on which rest block 32, 33 adjustably held by cords &c. secured to the framing of the hopper. The spaces 2 are divided off by partitions 3, 4, Fig. 5, connected respectively to side plates 5, 6 adapted to be reciprocated vertically by a double armed lever 10 actuated by stops 8, 9 on a reciprocating member 7 which carries an ejector 13. The cigarettes fall on to a table comprising vertical plates between which pass the partitions 3, 4 and plates which secure the ejector 13 to the member 7. On opposite sides of hopper 1 are receptacles 16 adapted to receive a layer of cigarettes on each movement of the ejector 13. The receptacles are supported by studs 18 which engage in threaded members 17 adapted to be rotated after each layer of cigarettes has been deposited in the adjacent receptacle 16 to lower it ready for the next layer. Instead of a single receptacle 16 at each side of the hopper, a number of receptacles 88, 39, Fig. 10, may be mounted on a frame 36 pivoted about a vertical axis 37 to permit a filled receptacle to be readily removed. The cigarettes are ejected from the hopper on to a table 42 which is moved upwards to thrust them through the bottom of the receptacle, retaining wires 43, 44 mounted in pivoted members 53, 54 being moved aside for their passage. When a receptacle is filled, the frame 36 is rotated automatically for half a turn and a box 56 is placed beneath the filled receptacle. By means of a knob 64 on a rod 62 connected to a plate 57, the pivoted members are opened and pressure on the knob transfers the cigarettes to the box. To adapt the device for feeding alternately unequal numbers of cigarettes, one or more of the ejectors is mounted separately and is adapted to be reciprocated on alternate strokes bv providing it with a recess adapted to be engaged by a pin on a reciprocating member when the support of the reciprocating member is raised by a cam. When oval cigarettes are to be treated the table is recessed to make them lie at the angle at which they will subsequently lie in the box. Round cigarettes are compressed laterally to take up the space occupied by the partitions 3, 4. For this purpose, angle bars 83, 84, Fig. 12, secured to parallel bars 87, 88, are adapted to be drawn apart by springs 94, 95, and to be pressed inwards by an arm 91 which engages between rollers 89, 90 on the bars. The bar 83 moves inwards the diameter of a cigarette and so avoids fouling the end ejector 13.
